Roa

ロア

A chimera who follows Greed. He was fused with a bull, granting him the strength of one, as shown to Al when he literally knocks Greed's head off with his hammer (Greed, naturally, recovers from this). He uses a hammer as his weapon and possesses the ability to transform into an enhanced version of himself featuring more bull-like traits, such as horns and increased strength. He is the only one of the three who fought in Ishval. He makes a cameo in the 15th volume, appearing as a background soldier after Roy Mustang's appearance on the battlefield.
